ZEBINA M. HIBBARD, OF ST. LOUIS, MICHIGAN.

STATION-INDICATOR.

SPECIFICATION forming part of Letters Patent No. 246,772, datedSeptember 6, 1881.

Application filed July 5, 1881. (ModeL) To all whom it may concern Be itknown that I, ZEBINA H. HIBBARD, of St. Louis, in the county of Gratiotand State of Michigan, have invented a new and ImprovedStation-Indicator, of which the tollowing is a full, clear, and exactspecification.

This invention is designed as an improvement on the station-indicatorfor which Letters Patent Nos. 209,122 and 214,776 were issued to meOctober 22, 1878, and April 2, 1879, respectively.

The invention consists in the combination, with the slattedindicator-belt, of a horizontal feed-shaft having a central rag-wheelfor preventing the passing of more than one of the belt-lags at a time;and it consists, further,-of a novel reversible device fixed on theoutside of the indicator-box for operating the indicator, all of whichwill be hereinafter set forth.

Figure 1 is a front elevation of the indicator with parts broken away toexhibit other parts. Fig. 2 is an end elevation of the same. Fig. 3 is avertical sectional elevation on line a; m, Fig. 1. Fig. 4 is a verticalsectionalelevation on line y y, Fig. 1.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents the box or case of the indicator, havingin its front a longitudinal opening, a, for the display of the names ofthe stations.

Within the boxA,journaled in the ends thereof,isthedriving-shat'tB,having fixed onit,near each end, within the box A,rectangular blocks 0 O, and having fixed on its center a rag-wheel, D,whose functions will be hereinafter set forth.

E represents the indicator-belt, consisting of a series of parallel lagsor slats, b I), connected at their ends by flexible strips 0, of clothor other suitable material, said lags or slats b I) having printed ormarked upon their faces names of stations, as shown at cl.

Secured upon the bottom of the box A, on the inside thereof, are one ormore partitions, F, preferably of sheet metal, that reach centrallyupward nearly to the shaft B, and serve to prevent the entangling of thebelt E when the device is in operation.

The rectangular blocks 0 G are designed to volves, and thereby preventsaid belt E from slipping.

On that end of the shalt B which extends through the end of the box A isrigidly secured a square block, B,preferably of metal.

Movably held in a vertical position on the end 10f the box A by staplesh h is a sliding dog, G, having as its head a rectangular open frame, G,that rests against the end of the box A, encircling the block B, saiddog-head G having its sides notched or shouldered on their inner edges,as shown at k k.

Directly and centrally above the head of the dog G is pivoted a swingingbar, H, whose upper and free end is connected with the dog-head G-to astud, m, in thetop thereof-by aspiral 'spring, K. When the bar H isthrown from the perpendicular to one side or the other, as shown in Fig.2, an inner edge of the dog-head G is brought by the tension of thespring K against a side of the block B, with a shoulder, 7c, just abovea corner of said block B, while the bar H rests in an angular positionon a lug or stop, on, as shown. \Vhen the parts are in this position adownward pull on the dog G will engage a shoulder, 70, upon thecontiguous corner of the block B, and thereby turn the shaft B a quarterof a revolution, so as to present at the opening a in the box A the nameof the next station. 011 then releasing the dog G it is drawn upward bythe spring K in position for another pull upon it, for the purpose ofgiving the shaft B another quarter-revolution, to present the name ofthe next station. When, on the return trip,'it is desired to display thenames of the stations in reverse order, the bar H is thrown over in theopposite direction, whereby the opposite side of the dog-head G isbrought against the block B, so that upon pulling down the dog G theshaft B is revolved in the reverse direction. As the indicator-belt E isturned over the shaft B said belt E piles or folds up in the bottom ofthe box A, as in- 2. In a station-indicator, the shaft B, prodicated inFig". 3, the partitions F preventing vided with the block B on its outerend, and. 15 the ends of said belt E from interfering with theopen-headed sliding dog G, provided with each other. internal shoulders,70 k, and secured on the end 5 Having thus described my invention, Iclaim of the indicator-case, the pivoted bar H, and
